3. The molar coefficient of light absorption of dithizone copper (II) in carbon tetrachloride at λeff = 550 nm is ten = 4.52 * 104. 100.00 ml of a solution of dithizone in CCl4 with a minimum optical density of 0.20 l = 5.0 cm was measured from a sample of an ingot weighing 1.00 g. Determine the mass fraction (%) of copper, which is determined using a sample of dithizone.
